BUNDLE-CARRYING ATTACHMENT FOR HARVESTERS.

SPECIFICATION formingpart of Letters Patent No. 677,621, dated July 2,1901. Application filed December 4, 1900. Serial No. 38,658. (No model.)

To all whom it may concern.- 3

Be it known that I, CARL N. BARGQUIST, a citizen of the United States,residing at Pelican Lake, in the county of Ottertail and State ofMinnesota, have invented certain new and useful Improvements inBundle-Carrying Attachments for Harvesters; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will en able others skilled in the art to which it appertains tomake and use the same.

My invention has forits object to provide an improved bundle-carryingdevice for use in connection with twine-binding harvesters; and to thisend it consists of the novel devices and combinations of deviceshereinafte described, and defined in the claims.

In accordance with my invention I employ a truck having one or moretraction-wheels and provide the same with canvases or endless conveyorsfor reoeiving and arighting the bundles, with an expansibleshock-holder, to

' which the bundles are delivered by said con- Veyer, and with adumping-bottom below the said shock-holder arranged tobe automaticallytilted when the bundles have accumulated sufficiently and to therebydump the accumulated bundles in a loose shock'or pile upon the ground.The truck of this bundlecarrier is preferably drawn by a single horse,and the inner end of the truck-frame is preferably, although notnecessarily, attached to the adjacent portion'of the harvester-frame byyielding joints or connections.

I will now describe specifically the preferred form of my improvedbundle-carrying device or attachment.

In the drawings which illustrate the said invention like charactersindicate like parts throughout the several views.

Figure 1 is a plan view'showing-the complete bundle-carrier.. Fig. 2 isa side elevation of the same looking from that side which abuts againstthe harvester, some parts of the said device, such as the canvases,being removed and Fig. 3 is'a vertical section on the line a m of Fig.1.

The numeral 1 indicates the platform-frame of the truck, the same havingupright brackets 2, 3, 4, and 5. As shown, the truck has twotraction-wheels 6 and 6. The tractionwheel 6 is located at the rear ofthe frame 1,

and its shaft 7 is journaled in boxes 8 on rearwardly projected portionsof the said frame 1. The traction-wheel 6 is located at the front andright-hand side of the frame 1, and its shaft 9 is journaled in bearings10, secured on the under side of the said frame.

As shown, the truck is adapted to be drawn by.a horse hitched to theshafts 11, and a frame-bar 12, secured at the left-hand side of.thetruck-frame, is adapted to be secured, preferably by flexible jointsafforded by any suitable devices, (not shown,) to the adjacent portionof the harvester-frame.

Canvas-rollers 13,14, 15, and 16 are mounted at their upper ends in thestandards 2, 3, 4, and 5, respectively, while at their lower ends theyare suitably mounted in longitudinallyext'ended beams 17 of theplatform-frame 1, which beams are, as shown, formed of Z-iron havingsuitable bearing-blocks 18. A pair of'horizontally-disposedcanvas-rollers 19 20 are mounted in suitable bearings 21, secured on thebeams 17. A platform-canvas 22 runs over..the rollers 19 and 20. Anarightingcanvas 23 runs over the rollers 15 and 16, and a pair ofslightly-separable butting-canvases 24 run over the rollers 13 and 14.The roller 13 has a collar 25, which spaces apart the canvases 24, andthe roller 14 has a packer or packing-arm 26, which works through thespace left between the said canvases 24.

It will be noted that the rollers 13 and 16, (see particularly Fig. 2,)which stand adjacent to the harvester, are very considerably inclined,while the outer rollers 14 and 15 are vertical or approximatelyvertical. This causes the canvases 23 and 24 to diverge upward in thevicinity of the harvester and to gradually approach parallelism as theyextend toward the said outer rollers. Outward and to the right of therollers 14 and 15 and in a horizontal plane approximately on a levelwith the top of the platform-canvas 22 is a dumping-platform 27, whichis pivoted between bars 28 and 29 on a pivot-shaft 30. A spring31,-attached to an eye 32, depending from the platform 27, and to an eye33on a depending bracket 34 of the frame 1, normally holds the saidplatform in a horizontal position, with its forward end against astop-bar 35, which bar 35 is, as shown, sup* ported at its ends by thebeams 23 and 29 of the platform. The numeral 36 indicates a concaveside-board or grain-guide disposed in board 36, so'that the saidplatform is left free to tilt on its pivot 30.

The gap left between the rear portion of the guide-board 36 and theouter and rear canvas-roller is spanned by an expansible or yieldingshock-holder, shown as afiorded by apair of curved spring-rods 39 and40, provided With eyes 41 at their ends, which freely slide, the one onthe body of the connected rod. The inner end of the rod 39 is suitablyconnected, as shown at 42, (see Fig. 2,) to the supporting bracket orupright 4, and the outer and forward end of the rod is connected, asshown at 43, (see Fig. 3), to a post 44, projected upward from theplatform-beam 29. It will also be noted by reference to Fig. 3 that therod 40 works through a slot in the guide-plate 36. The drivingconnections between the traction-wheels and the several endless canvaseswill now be traced.

The numeral 46 indicates a counter-shaft extended from front to rear ofthe machine, just outward of the platform-roller 19 and mounted insuitable hearings on the platformframe. This shaft 46 is connected atits rear end with the shaft 7 of the traction-wheel 6 by a pair ofbevel-gears 47, secured one on each of said shafts. At its forward endthe shaft 46 is connected with a shaft of the platform-roller 19 by apair of spur-gears 48, located one on each of said shafts. The shaft ofthe roller 16 is extended downward, as indicated at 49, and is providedwith a skewgear 50, whichmeshes with another skew-gear 51 on theintermediate portion of the shaft 46.

By the above connections the platform canvas or apron 22 and thearighting canvas or apron 23 will be driven from the traction- Wheel 6under the forward movement of the machine. To drive the butting canvasesor aprons 24, the shaft of the roller 14 is provided at its lower endwith abevel-pinion 52, which meshes with a bevel-wheel 53 on the innerend of the shaft 9 of the tractionwheel 6. Operation: The operation willbe substantially as follows: The bound bundles from the harvester willof course be discharged extending horizontally and will fall flatwiseonto the canvases or aprons which receive them. This bundle carryingattachment should be so connected to the harvester-frame that thedischarged bundles will fall onto the platform canvas 22 with the headsof the grain projecting onto the arighting canvas or apron 23 and withthe butt-ends of the grain presented to the so-called butting can-'vases or aprons 24. Under the action of these three canvases or apronsthe bundle will be gradually arighted or up-ended and will be stood uponits butt-end upon the platformcanvas 22 at approximately the time thatit reaches the outer portion of said canvas, at which time it is engagedby the packing-arm 26. By the packing-arm 26 the bundle is forced ontothe forward portion of the tilting platform 27 and against theguide-board 36. The bundles are thus deposited onto the platform 27 oneafter another and by the packing-arm 26 are gradually forced backward onthe said platform as they accumulate, the yieldingshock-holder affordedby the springrods 39 40 serving to permit this accumulation. When,however, the shocks have accumulated sufficiently on the rearwardportion of said platform 27, the spring 31 will be overcome and theplatform will tip and dump the entire load of bundles onto the ground ina loose shock or pile.

This machine is of course capable of many modifications within the scopeof my'invention. The terms canvases and aprons as applied to the endlesscarriers are herein used synonomously and in a generic sense to coverall forms of endless conveyers suitable for the above purposes.

What I claim, and desire to secure by Let ters Patent of the UnitedStates, is as follows:

1. A bundle-receiving device comprising an endless platform-apron, anarighting-apron gradually extending from an inclined toward a verticalposition from its receiving toward too its'delivery end, and a tiltingplatform receiving from said aprons.

2. A bundle-receiving device comprisinga platform-apron or endlesscarrier, and end less arighting and butting aprons cooperatingtherewith, which latter aprons gradually extend from inclined towardvertical positions from their receiving toward their deliv ery ends, atilting platform receiving from said aprons, and a yielding orexpansible shock-holder permitting the accumulation of bundles on thesaid tilting platform.

3. A bundle-carrying device, comprising the tilting platform 27 pivotedat 30, the guide board 36 following the forward and outer portion ofsaid platform, the overlapping springrods 39, 40, affording a shockholder and means for delivering the bundles grain end upward onto thesaid platform, substantially as described.

4. A bundle-carrying device comprising an endless platform apron orcanvas 22, the arighting-canvas 23 inclined at its receiving portion andmore closely approaching a vertical at its delivery portion, whereby thebundles are gradually arighted, and a dumping tic device receiving anaccumulation of bundles from the said aprons and automatically dumpingthe same, substantially as described.

5. In a bundle-carrying device, the combination with a truck havingtraction-wheels, of the endless canvases or conveyers 22, 23 and 24:,driven from said traction-wheels, which canvases 23 and 24: are inclinedat their receiving portions and gradually approach the vertical towardtheir delivery portions, the revolving packer 26 working at the deliveryportions of said aprons, the springheld dumping-platform 27 receivingfrom the said aprons, the guide-board 36 following the forward and outerportions of said dumpingplatform, and the overlapping spring-rods 39,4:0 aifording a yielding shock-holder substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
